Natural hazard-related disasters are rapidly increasing worldwide. Post-disaster waste management is important as debris impedes access of recovery crews, poses health hazards, increases length of residents’ stay in evacuation centres, and significantly adds to recovery costs. In Australia, waste management in business-as-usual times is the remit of local governments, yet during an emergency event the governance of disasters and disaster waste management is taken over by state level organizations. This shift creates tension between the roles and responsibilities of different actors, as well as uncertainty over access to infrastructure. Drawing on a mode of governing approach, we argue that implementing disaster governance in its current form is creating a fractured landscape of practice and policy that hinders progress towards sustainable debris management. A case study methodology was used to compare governance of municipal waste during business-as-usual times with governance of waste arising from disasters. Findings show that in disaster contexts, local governments are treated primarily as operational tools in the clean-up rather than as strategic partners. The siloed approach of organizations working on emergency management results in fragmented and unsustainable responses. Our results indicate that attempting to manage disaster waste without a pre-plan results in hurried and unsustainable solutions. The study contributes to the limited literature on disaster waste in Australia by providing empirical evidence of contested governance, demonstrating the need for context-specific disaster waste management plans, and extending the modes of governing framework to conditions where waste arises from severe disasters.

在世界范围内，与自然灾害有关的灾害正在迅速增加。灾后废物管理很重要，因为碎片妨碍恢复人员进入，对健康造成危害，增加居民在疏散中心停留的时间，并大大增加恢复成本。在澳大利亚，在一切照旧时期，废物管理是地方政府的职权范围，但在紧急事件期间，灾害治理和灾害废物管理则由州一级组织接管。这种转变造成了不同参与者的角色和责任之间的紧张关系，以及基础设施使用的不确定性。根据一种治理方法模式，我们认为以目前的形式实施灾害治理正在造成实践和政策的断裂，阻碍了可持续碎片管理的进展。采用案例研究方法比较了正常营业时期的城市废物治理与灾害产生的废物治理。调查结果表明，在灾害背景下，地方政府主要被视为清理工作的操作工具，而不是战略合作伙伴。从事应急管理工作的组织的孤立做法导致了零碎和不可持续的反应。我们的研究结果表明，试图在没有预先计划的情况下管理灾害废物会导致匆忙和不可持续的解决方案。该研究通过提供有争议的治理的经验证据，证明需要针对具体情况的灾害废物管理计划，并将治理框架模式扩展到严重灾害产生废物的情况，为澳大利亚灾害废物的有限文献做出了贡献。

The concept of integrated risk management (IRM) has developed as a response to more interconnected and complex contexts. To investigate how the concept is used and what is meant with integration in the scientific literature, a research profiling was carried out across all kinds of risk management applications. 1094 publications from scientific journals, conference proceedings, and books were included. The study period of 21 years showed a steady increase in the use of IRM, especially for risk management in the private sector and for natural hazard risks. 634 of the publications were published in 331 different journals, representing a large range of scientific disciplines. Only 30 % of the publications were connected by internal referencing. 86 different specific risks were identified and clustered into seven risk clusters. Two major types of integration were identified: firstly, of different aspects of the risk itself or within the risk management process, and secondly, between the risk management process and a wider context of other objectives and processes related to business, society, or ecosystems. The integration of natural hazard risks mainly was in relation to societal processes and ecosystems, whereas integration of business-related risks took place mainly within the business sector. Overall, the literature on IRM is fragmented, with a few exceptions where discourses have developed around certain risks like flood risk and enterprise risk. The development of a more general understanding of integration across different fields of risk management would benefit analyses and decision-making in an increasingly interconnected world.

综合风险管理（IRM）的概念是为了应对更加相互关联和复杂的情况而发展起来的。为了调查这个概念是如何使用的，以及科学文献中整合的含义是什么，我们对各种风险管理应用进行了研究分析。包括来自科学期刊、会议记录和书籍的1094份出版物。这项为期21年的研究表明，内部风险管理的使用稳步增加，特别是在私营部门的风险管理和自然灾害风险方面。其中634篇发表在331种不同的期刊上，代表了广泛的科学学科。只有30%的出版物是通过内部引用连接起来的。他们确定了86种不同的特定风险，并将其归为7类风险。确定了两种主要类型的集成：第一，风险本身的不同方面或风险管理过程中的集成；第二，风险管理过程与与业务、社会或生态系统相关的其他目标和过程的更广泛背景之间的集成。自然灾害风险的整合主要与社会进程和生态系统有关，而与商业有关的风险的整合主要发生在商业部门内部。总的来说，关于IRM的文献是支离破碎的，只有少数例外，这些文献是围绕洪水风险和企业风险等特定风险发展起来的。对不同风险管理领域之间的整合形成更普遍的理解，将有利于在日益相互关联的世界中进行分析和决策。

This study proposes an enhanced macroseismic framework for regional seismic risk assessment that accounts for litho-stratigraphic site effects and refines building exposure modelling using open-access spatial datasets. The methodology is applied to the Campania region in southern Italy, combining official census data with high-resolution building height estimates to disaggregate structural typologies into three classes: low-rise (1-3 storeys), mid-rise (4-7 storeys), and high-rise (≥ 8 storeys), associated with distinct vibration period ranges. In addition, the year of construction and the conservation status of the buildings are considered to refine the vulnerability assessment. Seismic hazard is quantified through period-dependent spectral acceleration, which is then converted to macroseismic intensity. The results reveal significant spatial variability in damage scenarios and repair costs, driven by both structural typology and site conditions. Metropolitan areas exhibit the highest vulnerability and economic impact, with site amplification increasing estimated regional repair costs by over 60 %. The proposed GIS-compatible methodology offers a replicable and policy-relevant tool for supporting seismic risk mitigation, urban resilience planning, and targeted retrofitting strategies.

本研究提出了一个用于区域地震风险评估的增强宏观地震框架，该框架考虑了岩石地层场地效应，并使用开放获取的空间数据集改进了建筑物暴露模型。该方法应用于意大利南部的坎帕尼亚地区，将官方人口普查数据与高分辨率建筑高度估计相结合，将结构类型分为三类：低层（1-3层）、中层（4-7层）和高层（≥8层），与不同的振动周期范围相关。此外，还考虑了建筑的建造年份和建筑物的保护状况，以完善脆弱性评估。通过周期相关的频谱加速度来量化地震危险性，然后将其转换为大震烈度。研究结果显示，受结构类型和场地条件的影响，损坏场景和修复成本在空间上存在显著差异。大城市地区表现出最高的脆弱性和经济影响，场地扩大使估计的区域修复成本增加了60%以上。拟议的与地理信息系统兼容的方法为支持减轻地震风险、城市复原力规划和有针对性的改造战略提供了可复制且与政策相关的工具。

This study presents a probabilistic hazard framework for assessing wildland-urban fire hazards triggered by wind-induced failures in electrical distribution systems. The framework integrates wind fragility analysis of aging utility poles, ignition probability modeling, and fire spread simulations using FARSITE. The analytical fragility curves were developed with electrical component data from an electrical distribution network in Oklahoma. Monte Carlo methods were used to evaluate failure, ignition, and fire propagation across varying wind conditions. Anthropogenic hazard maps were generated to identify high burn probability and fire intensity areas. Exposure maps for electrical poles and conductors were developed to show the connection between self-induced electrical fires and the probabilistic fire exposure to other network assets. Results show that aging electrical poles significantly increases network failure and ignition risk, revealing that electrical distribution networks can pose a fire hazard to the very communities they serve. Fires ignited by failed poles spread rapidly under high wind conditions, with flame lengths and heat intensity escalating sharply beyond 28 m/s. Exposure maps show network components most frequently affected by fire, offering utilities a basis for targeted hardening and vegetation management. For emergency responders, the spatial patterns of ignition and burn probability support hazard scenario-based planning and resource deployment under fire weather conditions.

本研究提出了一个概率危害框架，用于评估配电系统中由风力引起的故障引发的荒地-城市火灾危害。该框架集成了老化电线杆的风脆弱性分析、着火概率建模和使用FARSITE的火灾蔓延模拟。分析脆性曲线是根据俄克拉荷马州一个配电网络的电气元件数据开发的。蒙特卡罗方法用于评估失效，点火和火灾传播在不同的风条件。绘制了人为危害图，以确定高燃烧概率和火灾强度区域。开发了电线杆和导体的暴露图，以显示自感电气火灾与其他网络资产的概率火灾暴露之间的联系。结果表明，老化的电线杆显著增加了网络故障和着火风险，表明配电网络可能对其所服务的社区构成火灾危险。失效电线杆引燃的火灾在大风条件下迅速蔓延，火焰长度和热强度急剧上升，超过28米/秒。暴露图显示了最常受火灾影响的网络组件，为公用事业公司提供了有针对性的硬化和植被管理的基础。对于应急响应人员来说，着火和燃烧概率的空间模式支持火灾天气条件下基于危险场景的规划和资源部署。

Extreme rainfall events in urban environments are a well-known issue in society due to the multiple impacts that can induce, which are expected to increase due to climate change effects. During high intensity rainfall events, an often overlooked risk is the threat to pedestrian stability posed by overland flow forces that can induce instability when crossing the streets. To analyze this gap, we employ hydrodynamic modeling in a catchment in São Paulo city, Brazil, under climate change conditions to assess human instability with multiple levels of vulnerability, according to the age, gender, weight and height of the people. Our results allowed us to identify zones with potential risk that tend to increase along the 21st century, where children are the most significant vulnerability group to potential injuries compared to adults. We observed that human instability is more sensitive to pulses of rainfall intensity than to the total rainfall volume, indicating that even low volume rainfall events can pose a considerable danger to pedestrians. The Results provide valuable insights to decision-makers for better urban planning against challenges exacerbated by climate change in the future. This research, as the first of its kind, helps to identify risk zones for the implementation of measures to reduce both flow depth and velocity. In addition, this study offers a potential tool for enhancing communication and knowledge sharing with society, aiming to influence the perception of this type of risk, which is often underestimated, especially by pedestrians, in order to help prevent injuries or potential fatalities.

城市环境中的极端降雨事件是一个众所周知的社会问题，因为它可以引发多种影响，预计由于气候变化的影响，这种影响将会增加。在高强度降雨期间，一个经常被忽视的风险是地面流力对行人稳定性造成的威胁，这可能导致过马路时不稳定。为了分析这一差距，我们在气候变化条件下，在巴西圣保罗的一个集水区采用了水动力学模型，根据人们的年龄、性别、体重和身高，评估了具有多重脆弱性的人类不稳定性。我们的研究结果让我们确定了21世纪有潜在风险的区域，与成年人相比，儿童是最容易受到潜在伤害的群体。我们观察到，人类的不稳定性对降雨强度的脉冲比对总降雨量的脉冲更敏感，这表明即使是小降雨量事件也会对行人造成相当大的危险。研究结果为决策者更好地进行城市规划，应对未来气候变化加剧的挑战提供了宝贵见解。该研究是同类研究中的第一个，有助于确定风险区域，以便实施降低流深和流速的措施。此外，该研究还提供了一种潜在的工具，可以加强与社会的沟通和知识共享，旨在影响人们对这类风险的认识，尤其是行人，从而帮助预防伤害或潜在的死亡。

Flooding remains one of the most damaging natural hazards, underscoring the need for a better understanding of public perceptions of flood risk to support preparedness and mitigation. This study compares risk perceptions from a national online survey of 918 respondents with FEMA flood maps. We define the risk perception gap as the difference between respondents' perceived flood risk and FEMA's flood zone classifications, and we examine its drivers. Multinomial logistic regression was used to assess how socioeconomic characteristics, spatial context, and latent variables from Protection Motivation Theory (PMT) influence whether individuals perceive their flood risk as higher, lower, accurate, or express uncertainty about it. Many residents living in FEMA-designated floodplains perceive their flood risk as lower.

The results revealed that higher perceived self-efficacy was associated with either elevated perceived flood risk or increased uncertainty. Greater perceived susceptibility was correlated with less uncertainty. People who live near water bodies perceive flood risk differently from what FEMA maps indicate, reflecting polarized perceptions of flood risk. A lack of awareness about elevated terrain (necessary for avoiding rising flood waters) tends to downplay their flood risk. Older individuals exhibited less uncertainty about their property's flood risk.

These findings highlight the need for targeted, place-based flood-risk communication strategies that address socio-cognitive and geographical factors. These strategies may help to reduce perception gaps, improve community preparedness and risk literacy, and strengthen resilience to flooding. The potential underestimation of flood risk in FEMA flood maps highlights the need for improved map accuracy and localized risk assessments.

洪水仍然是最具破坏性的自然灾害之一，因此需要更好地了解公众对洪水风险的看法，以支持备灾和减灾。这项研究比较了918名受访者的全国在线调查与联邦应急管理局洪水地图的风险认知。我们将风险感知差距定义为受访者感知的洪水风险与FEMA的洪水区分类之间的差异，并研究了其驱动因素。使用多项逻辑回归来评估社会经济特征、空间背景和保护动机理论（PMT）的潜在变量如何影响个体对洪水风险的感知是高、低、准确还是表达不确定性。许多居住在联邦应急管理局指定洪泛区的居民认为他们的洪水风险较低。结果显示，更高的自我效能感与更高的洪水风险或不确定性相关。更大的感知敏感性与更少的不确定性相关。居住在水体附近的人们对洪水风险的认知与联邦应急管理局地图上显示的不同，反映了人们对洪水风险的两极看法。缺乏对高地的认识（这是避免洪水上涨的必要条件）往往会低估洪水的风险。老年人对其财产的洪水风险表现出较少的不确定性。这些发现强调需要有针对性的、基于地点的洪水风险沟通战略，以解决社会认知和地理因素。这些战略可能有助于缩小认识差距，提高社区准备和风险素养，并加强对洪水的抵御能力。联邦应急管理局洪水地图可能低估了洪水风险，这凸显了提高地图准确性和局部风险评估的必要性。

Community-led disaster resilience is an emerging concept in disaster risk reduction that emphasises local leadership, grassroots coordination and adaptive strategies to enhance preparedness and recovery. It is based on community knowledge, lived experience of emergency events and readiness to work collaboratively to towards improving resilience, preparedness and recovery, often with support from external organisations.

This paper explores community-led resilience models through the case study of the Australian Red Cross Community-Led Resilience Teams (CRT) program in regional New South Wales in Australia. Drawing on qualitative data from the formative evaluation of the program in 2024, we analyse the strengths of community-led resilience efforts including their ability to enhance trust, social cohesion, and responsiveness to local needs. We also critically examine key challenges, such as sustaining long-term engagement, navigating resource limitations, and ensuring inclusivity, particularly in reaching marginalised groups.

Drawing from our data, we present a four-factor framework for practitioners, indicating how community-led resilience can be supported: 1. Relationships and inclusive networks for sharing knowledge, skills, resources and enhancing community cohesion; 2. Supporting motivation by engaging at the appropriate time, enabling growth mindsets and risk perception; 3. Supporting emerging community-backed leaders willing and able to step up, and 4. Developing skills and knowledge and supporting mental capacity.

This paper contributes to the broader conceptual understanding of how communities can be supported and empowered to drive their own resilience-building strategies. We incorporate evaluation practice and resilience theory to offer insights for policymakers and practitioners on fostering sustainable and inclusive community resilience.

社区主导的抗灾能力是减少灾害风险的一个新兴概念，它强调地方领导、基层协调和适应性战略，以加强备灾和恢复。它的基础是社区知识、对紧急事件的实际经验，以及在外部组织的支持下，为提高复原力、防备和恢复能力而协同工作的意愿。本文通过对澳大利亚新南威尔士州地区澳大利亚红十字会社区领导的复原力小组（CRT）项目的案例研究，探讨了社区主导的复原力模式。根据2024年该项目形成性评估的定性数据，我们分析了社区主导的韧性工作的优势，包括增强信任、社会凝聚力和对当地需求的响应能力。我们还严格审查了关键挑战，如维持长期参与、应对资源限制、确保包容性，特别是在接触边缘化群体方面。根据我们的数据，我们为从业者提出了一个四因素框架，表明如何支持社区主导的弹性：分享知识、技能、资源和增强社区凝聚力的关系和包容性网络；2. 通过在适当的时间参与来支持动机，使成长心态和风险感知成为可能；3. 3 .支持有意愿和能力的新兴社区支持的领导人；发展技能和知识，支持心智能力。本文有助于从更广泛的概念上理解如何支持和授权社区推动其自身的复原力建设战略。我们将评估实践和弹性理论结合起来，为政策制定者和实践者提供关于培养可持续和包容性社区弹性的见解。

The interdependence between urban infrastructure systems and community building portfolios is becoming a critical issue in urban seismic resilience. Existing studies primarily focus on the impacts of service disruptions of infrastructure systems on the functionality of the community building portfolio (BPS). This study proposes a framework that can quantitatively describe how BPS affects the performance and recovery of infrastructure systems under seismic scenarios, where population displacement is utilized to bridge the interconnections between BPS and the infrastructure system. Firstly, the seismic damage to the building portfolios and water distribution system is assessed using fragility models. Then, the post-earthquake population redistribution in various areas is evaluated according to the damage states of buildings, and the dynamic migration of evacuated populations during post-earthquake building repairment is estimated. Subsequently, the seismic performance of the Water Distribution Systems (WDSs) is evaluated based on the water demand satisfaction ratio, which explicitly accounts for the spatiotemporal variations in water demand resulting from population migration. Finally, the proposed framework is implemented in the seismic performance analysis of BPS and WDS in Shelby County, Tennessee. The results indicate that the seismic damage to BPS significantly affects the water demand of WDS, resulting in a 37 % reduction in WDS system performance and a nodal performance reduction of up to 76 %. This study provides innovative insights into the interdependence between infrastructure systems and community-building portfolios.

城市基础设施系统和社区建筑组合之间的相互依存关系正在成为城市抗震能力的关键问题。现有的研究主要集中在基础设施系统服务中断对社区建设组合（BPS）功能的影响。本研究提出了一个框架，可以定量描述地震情景下BPS如何影响基础设施系统的性能和恢复，其中人口流离失所被用来弥合BPS和基础设施系统之间的相互联系。首先，利用易损性模型对建筑组合和配水系统进行了震害评估。然后，根据建筑物的破坏状态，评估各地区的震后人口分布情况，估计震后建筑修复过程中疏散人口的动态迁移。在此基础上，基于用水需求满足率对配水系统的抗震性能进行了评价，该指标明确考虑了人口迁移引起的用水需求时空变化。最后，将提出的框架应用于田纳西州谢尔比县BPS和WDS的抗震性能分析中。结果表明，地震对BPS的破坏显著影响了WDS的需水量，导致WDS系统性能下降37%，节点性能下降高达76%。本研究对基础设施系统和社区建设组合之间的相互依存关系提供了创新的见解。

Increased flooding is becoming more prevalent under an increasingly variable future of weather extremes, highlighting the need for effective mitigation strategies. Different flood mitigation measures are available, ranging from classical structural (grey) solutions to nature-based solutions (NbS). This study assessed and compared the hydrological effectiveness, cost-effectiveness, and public perception of green (NbS), grey, and hybrid flood mitigation measures in the Gradaščica River catchment, Slovenia. For the hydrological assessment, a SWAT + model simulated wetland, retention polder, and dam scenarios. Results showed that wetlands had a minimal effect on flood hazard, reducing flood peaks by up to 3 %, while retention polders and dams reduced flood peaks by 51 % and 73 % and flood volumes by 28 % and 58 %, respectively. The economic analysis found wetlands to be less cost-effective than retention polders and dams. However, it should be noted that wetlands provide additional diverse co-benefits. The public perception analysis revealed significant discrepancies in perceived effectiveness, feasibility, and acceptability of flood mitigation measures across target groups, including the general public, water engineers, researchers, and agricultural advisors. While most groups ranked dams as most effective and wetlands as least effective, aligning with hydrological findings, researchers held a directly opposing view, and the public generally overestimated the performance of green measures. By examining hydrological effectiveness, cost-effectiveness, and public perception across flood mitigation measures, the research highlights the need to integrate multidisciplinary approaches to develop robust flood management strategies – an essential lens as communities confront escalating climate-driven flood risks.

在未来极端天气变化越来越大的情况下，洪水的增加正变得更加普遍，这突出表明需要制定有效的减灾战略。可以采取不同的防洪措施，从经典的结构（灰色）解决方案到基于自然的解决方案（NbS）。本研究评估并比较了斯洛文尼亚Gradaščica河流域的水文有效性、成本效益和公众对绿色（NbS）、灰色和混合洪水缓解措施的看法。为了进行水文评估，SWAT +模型模拟了湿地、保留区圩田和水坝情景。结果表明，湿地对洪涝灾害的影响最小，最多减少3%的洪峰，而保留圩田和水坝分别减少51%和73%的洪峰和28%和58%的洪水量。经济分析发现，湿地的成本效益不如圩田和水坝。然而，应该指出的是，湿地提供了其他各种各样的共同利益。公众感知分析显示，包括普通公众、水利工程师、研究人员和农业顾问在内的目标群体对防洪措施的感知有效性、可行性和可接受性存在显著差异。虽然大多数团体将水坝评为最有效的，而将湿地评为最无效的，与水文调查结果一致，但研究人员持直接反对意见，公众普遍高估了绿色措施的表现。通过检查水文有效性、成本效益和公众对洪水缓解措施的看法，该研究强调了整合多学科方法以制定强有力的洪水管理战略的必要性——这是社区面临不断升级的气候驱动洪水风险的一个重要视角。

Given the challenges facing the UK in relation to health security, the development and evaluation of risk communication resources is essential to support public response and recovery to adverse events. While online resources are frequently utilised in emergency preparedness and response contexts, there is limited research focusing on the impact of these resources on attitudes and behaviours related to preparedness. The aim of the current study was to examine the impact of a newly developed UK Government website (‘Prepare’) on behaviours, knowledge and attitudes associated with emergency preparedness and resilience. The results revealed that while there were no significant changes in attitudes towards preparedness or public perceptions of resilience following website engagement, participants who viewed the ‘Prepare’ website had completed a significantly higher number of individual preparedness actions post website engagement (compared to pre website engagement) than had those who viewed a control website. While these results are promising, future research should further examine the impact of online risk communication materials to understand their role in incident response and recovery.

鉴于联合王国在卫生安全方面面临的挑战，开发和评估风险沟通资源对于支持公众应对和恢复不良事件至关重要。虽然在线资源经常用于应急准备和反应，但关注这些资源对与准备有关的态度和行为的影响的研究有限。本研究的目的是检查新开发的联合王国政府网站（“准备”）对与应急准备和复原力有关的行为、知识和态度的影响。结果显示，虽然参与网站后对准备的态度和公众对恢复力的看法没有显著变化，但观看“准备”网站的参与者在参与网站后（与参与网站前相比）完成的个人准备行动数量明显高于观看对照网站的参与者。虽然这些结果很有希望，但未来的研究应该进一步检查在线风险沟通材料的影响，以了解它们在事件响应和恢复中的作用。
